Insertion of a urinary catheter, or indwelling catheterization as it is clinically referred to, is an invasive medical procedure that can be painful. For normal non-pathological states, such as preoperative prophylactic indwelling catheterization, the insertion of a urinary catheter is completed within approximately 1 minute for both men and women. If the patient’s cooperation is poor, the time may be appropriate and need to be extended. However, for pathological states, the time to insert a urinary catheter is determined by the condition. If stones are present in the urethra, it is relatively difficult to insert the urethra and there is even a possibility of failed urethral insertion. For most elderly male patients, who have varying degrees of prostate enlargement, the time to insert a urinary catheter may be about 2-3 minutes. Because of the narrowing of the posterior urethra due to hyperplasia that can occur after the urethra enters the posterior urethra, it is difficult to keep the urethra in place. If necessary, a specialized urologist is needed to complete the ureter insertion.
